Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses, and computer readable storage media for discontinuous reception (DRX)-enabled multipath (MP) communications. In a method, a first device receives a DRX configuration for a direct path between the first device and a second device and an indirect path between the first and second devices via a third device. The DRX configuration comprises at least one of a first DRX configuration or a second DRX configuration. The first DRX configuration is used for a first communication between the first and second devices on the direct path, and the second DRX configuration is used for a second communication between the first and third devices on the indirect path. Based on the received DRX configuration, the first device communicates with the second device on the direct path and with the third device on the indirect path.

Abstract: A method may include monitoring, by a source user equipment communicating with a destination user equipment by an indirect communication path via a relay user equipment, sidelink control information from the relay user equipment. The method may also include determining a first set of conditions and a second set of conditions based on the sidelink control information received from the relay user equipment. The method may further include transmitting, when the first set of conditions is met, at least one of a first sidelink message to the destination user equipment according to a first pattern, or a second sidelink message to the relay user equipment according to a second pattern. In addition, the method may include monitoring a sidelink feedback from the destination user equipment to the relay user equipment when the second set of conditions is met according to a third pattern.

Abstract: A UE operates in a system where a source UE communicates using SL communications with a destination UE and detects a SL coverage issue with the sidelink communications between the source and destination UEs. The UE sends, to at least the destination UE, an announcement concerning at least one of the sidelink coverage issue or the UE being available as a relay UE candidate for an indirect path to the destination UE. The destination UE receives the announcement and communicates with the UE to set up and use the indirect path.

Abstract: In an example embodiments, sending, by a remote user equipment (UE) of a source cell, towards a network node of the source cell a measurement report including a candidate relay (CR) list, wherein the CR list includes at least a cell identification for at least one CR UE for an indirect path switching from the source cell to a target cell associated with a CR UE; detecting a change of a serving cell or camping cell of the CR UE from the target cell to another cell based on receiving from the CR UE at least one message that indicates at least one cell identification for the CR UE is different than reported; and based on the detecting, sending an updated measurement report towards the network node triggering renewing a path switch decision or initiating a radio resource control connection re-establishment procedure with the source cell or the target cell.

Abstract: A method comprising receiving an indication from a transmitting terminal device indicative of a sidelink resource reserved for receiving a subsequent sidelink transmission from the transmitting terminal device, detecting that the subsequent sidelink transmission is not received from the transmitting terminal device over the reserved sidelink resource, determining a sidelink complementary resource set window, and monitoring the sidelink complementary resource set window for receiving the subsequent sidelink transmission from the transmitting terminal device.

Abstract: One embodiment is directed to a method comprising receiving a configuration of a resource pool for sidelink communication; determining there is a need for assistance from one or more other UEs in proximity in resource reservation or resource selection from the configured resource pool for SL communication of the UE; sending a request over SL for the needed assistance from the one or more other UEs in proximity based on the determination; monitoring and receiving possible response from the one or more other UEs in proximity which may include recommended resource from the configured resource pool for the request of UE; selecting resource for SL communication of the UE by taking into account the received response; and performing SL communication using the selected resource.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of Channel Occupancy Time (COT) for Sidelink (SL) communication in Unlicensed band (U-band). The method includes receiving, at a first device and from a second device, configuration information associated with a COT at least for a SL transmission of the first device on an unlicensed resource pool allocated for the first device, the configuration information at least indicating whether a listen before talk procedure is required to be performed at the first device within the COT before the SL transmission; and performing the SL transmission within the COT based on the configuration information. In this way, the COT sharing mechanism can be used for SL communications in U-band and therefore a sensing procedure for resource selection may not be impacted by the LBT procedure.

Abstract: Various example embodiments provide efficient burst transmission of duplicated data packets. A data burst comprising multiple data packets may be configured to be transmitted on a first transmission leg. The data burst may be further configured to be transmitted on a second transmission leg with a different order of data packets. A reception status of the data packets may be configured to be determined based on transmissions on the first and second transmission legs and non-acknowledged data packets may be retransmitted on the first transmission leg and/or the second transmission leg. Apparatuses, methods, and computer programs are disclosed.

Abstract: An intermediate apparatus and method for relaying data from a remote wireless device to a base station with reduced latency is discussed. The method includes the steps of receiving a transmission having control information and data. Determining from the control information that the data is to be forwarded to a wireless communication node and that a future data transmission comprising data to be forwarded is scheduled. Estimating from the control information an amount of the data in the future data transmission. Generating a resource request comprising the estimated amount of data in the future data transmission and transmitting, the resource request towards the wireless communication node.
